In the case of the A18 Pro in the Neo, the memory is integrated directly into the package which is shared between the CPU, GPU and Neural Engine.

Naturally it's faster to have all of this in the same package, with memory bandwidth up to 400 GB/s.

Intel and AMD are heading in the same direction.

I had not picked up on these guys doing 400 GB/s; that's nearing discrete levels of bandwidth.
